[0002] The pedestrian roadbed is usually formed by adding asphalt materials to mineral materials. Before paving the road surface, it is necessary to ensure the cleanliness of the road base layer and the rationality of the density and thickness of the base surface. Rolling equipment is needed to roll and level the road base layer.
[0003] When existing base paving equipment is rolling asphalt roads, it is easy for asphalt to stick to the rolling roller, affecting the roundness of the rolling roller, resulting in uneven roads during rolling, affecting the pavement paving effect.
[0004] In the prior art, although the above problems are solved by sprinkling water or cleaning the rolling roller, the sprinkling method is easy to affect the water content of the pavement and is difficult to control. The sprayed water is easy to accumulate on the incompletely formed road surface, thereby affecting the quality of the road surface and causing instability. In addition, the sprayed water is difficult to be evenly distributed on the rolling roller, thereby affecting the effect that the rolling roller is not easy to stick to asphalt.
[0005] However, the method of cleaning the rolling roller is difficult to achieve a thorough cleaning effect, and it is easy to cause residues and uneven rolling. It is also easy to increase the friction between the residues and the cleaning structure on the rolling roller, thereby increasing the wear of the rolling roller and further affecting the rolling effect.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] like Figure 1 As shown, the utility model provides an automatic paving equipment for a sidewalk base, including a body 10 with a rolling roller 11, a coating roller 20 is movably arranged on one side of the body 10 close to the rolling roller 11, a material guiding mechanism 30 is fixedly installed on the body 10, and the liquid in the material guiding mechanism 30 is coated on the surface of the rolling roller 11 by abutting against the coating roller 20 and the rolling roller 11 in sequence to form a material transfer structure, and a material return mechanism 40 is movably arranged below the material guiding mechanism 30, and the material return mechanism 40 is located directly below the coating roller 20 and movably abuts against the outer wall of the rolling roller 11 to form a liquid return structure for removing impurities.
[0029] The utility model adopts a movable abutment form to form a uniform coating structure, stores the liquid in the material guiding mechanism so that it can be fully accumulated on one side of the coating roller, and then transfers an appropriate amount of liquid to the outer wall of the rolling roller by abutting against the coating roller. The indirect coating form can reduce the direct accumulation of excess liquid on the rolling roller, which is beneficial to uniformly coat the rolling roller and pre-treat the rolling roller at the same time, thereby achieving the purpose of not easy to stick to residues and improving the rolling effect.
[0030] The anti-adhesive agent is accumulated in the material guiding mechanism 30 so as to be fully covered on the coating roller 20. The coating roller 20 is rotated and abutted against the rolling roller 11 to evenly transfer the anti-adhesive agent to the surface of the rolling roller 11, so that the rolling roller 11 is not easily sticky to residues such as asphalt during the rolling process. At the same time, the leaked anti-adhesive agent is collected at the bottom by the return mechanism 40. The return mechanism 40 abuts against the rolling roller 11 to scrape off any residues that may exist on the surface of the rolling roller 11, and then rotates to the coating roller 20 for coating. The dual treatment of anti-adhesion and cleaning greatly reduces the stickiness on the surface of the rolling roller 11, and also helps to reduce the wear on the rolling roller 11.
[0031] like Figure 1 and Figure 2 As shown, the material guiding mechanism 30 includes an arc-shaped agent storage bin 31 , and a sponge strip 32 is provided on the side of the agent storage bin 31 in contact with the coating roller 20 . The length of the sponge strip 32 is greater than the length of the coating roller 20 .
[0032] The anti-adhesive agent is accumulated by the agent storage bin 31 so that it can fully cover one side of the coating roller 20, and is evenly coated on the outer wall of the coating roller 20 by the sponge strip 32 to form a coating of a certain thickness, which facilitates the coating roller 20 to transfer the anti-adhesive agent to the surface of the rolling roller 11.
[0033] The length of the sponge strip 32 is advantageous for covering the entire length of the coating roller 20 , so that the coating roller 20 can coat the anti-sticking agent on the entire surface of the laminating roller 11 .
[0034] like Figure 1 and Figure 2 As shown, the outer layer of the coating roller 20 is provided with a silicone layer 21 , and the length of the coating roller 20 is greater than the length of the laminating roller 11 .
[0035] The contact between the silicone layer 21 and the rolling roller 11 can reduce the wear of the rolling roller 11, which is conducive to better transfer of the anti-adhesive agent to the surface of the rolling roller 11. At the same time, the length of the coating roller 20 can cover the length of the rolling roller 11, so as to facilitate uniform coating of all parts of the rolling roller 11.
[0036] like Figure 3 and Figure 4 As shown, the material return mechanism 40 includes a liquid return box 41, the width of the liquid return box 41 is greater than the width of the combination of the material guide mechanism 30 and the coating roller 20, and a long row of brushes 42 that are movably in contact with the laminating roller 11 are provided on one side of the liquid return box 41, and the end of the long row of brushes 42 close to the liquid return box 41 is inclined downward;
[0037] The long row of brushes 42 is movably connected to the inner wall of the liquid return box 41 through a clamping block 43 , and the inner wall of the liquid return box 41 is provided with a clamping groove which is at an inclined angle and matches the clamping block 43 .
[0038] The long row of brushes 42 is connected to the card slot through the card block 43 and can be installed on one side of the liquid return box 41 at an inclined angle, so that it is convenient to disassemble and replace.
[0039] According to the forward direction of the rolling roller 11, a long row of brushes 42 is arranged under the coating roller 20 to facilitate pre-treatment of the rolling roller 11, to remove impurities that may remain on the rolling roller 11, to maintain a clean coating operation, and to guide the liquid dripping from above into the liquid return box 41.
[0040] like Figure 1 As shown, a material storage box 12 is arranged on the machine body 10 , and a material discharge pipe 13 is arranged at the discharge end of the material storage box 12 , and the material discharge pipe 13 is vertically arranged just above the agent storage bin 31 .
[0041] A valve is provided at the liquid outlet end of the discharge pipe 13. An appropriate amount of anti-adhesive agent is transported to the storage bin 31 through the discharge pipe 13 as needed, so that the anti-adhesive agent in the storage bin 31 can be accumulated to a certain height, which is beneficial for adhering to the surface of the coating roller 20 for transfer while the coating roller 20 rotates. When the anti-adhesive agent in the storage bin 31 is less, it is transported again for replenishment.
[0042] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
